Replace MSE SDK with direct access to ACDL

[herzog31]

Description

• Replace Magento Storefront Events SDK and instead write events directly into ACDL
• For categories, the widget adds a categories query to retrieve category information.
  • This category information is required to set the categoryContext required for product recommendations.
  • To send this query, the category id is required which has to be provided via currentCategoryId.
  • When currentCategoryId is provided, it will also be used as filter for productSearch.

Motivation and Context

• Improve performance

Is this removing events for sensei? My understanding is that the MSE SDK is needed to send events to sensei. Is this possible through ACDL? ( I have a limited understanding here lol)

[herzog31]

@MichaelHeinzman MSE SDK is a wrapper around ACDL which introduces some overhead. ACDL itself is pending some improvements in this regard as well. For Edge Delivery storefronts in particular, we try to keep the implementation as lightweight as possible. From an eventing / Sensei perspective, this PR does not change or break any existing functionality.

Oh okay thank you, I'll look into it more then.

@herzog31 Should this be an or condition instead? Everywhere else seems to have a fallback of category path first, then category id.
This is particularly an issue with Edge Delivery since the content is the same across all backend environments, and category IDs vary per environment. We would need to make an initial graphql call to get the category ID based on the category path and then initiate this widget
